Recently, model independent diagrammatic approach is used to
analyze the charm decays [1]}. All two-body hadronic
decays of \(D\)  mesons can be expressed in terms of some distinct
topological diagrams within the SU(3) flavor symmetry, by extracting
the topological amplitudes from the data [2]}. Since
the recent measurements of \(D_s^+\rightarrow \pi ^+\rho ^0\)  [3]} and
\(D_s^+\rightarrow \pi ^+\omega \)  [4]} give a strong constraint on the
\(W-\) annihilation amplitudes, one cannot find a nice fit for \(A_P\) 
and \(A_V\)  in the diagrammatic approach to the data with \(D_s^+\rightarrow \bar{K}^{*0}K^+,\bar{K}^0K^{*+}\)  simultaneously. Compared to the
calculations in the model-independent diagrammatic approach
[2]}, our hybrid method
gives more predictions for the \(PV\)  modes in which the
predictions are consistent with the experimental data. It is
questioned that the measurement of
\(Br(D_s^+\rightarrow \bar{K}^0K^{*+})=(5.4\pm 1.2)\%\) ,[6]} which was taken two decades ago, was
overestimated.
Since \(|C_V|<|C_P|\)  and \(A_V\approx A_P\)  as a consequence of very small rate of \(D_s^+\rightarrow \pi ^+\rho ^0\) ,
it is expected that \(Br(D_s^+\rightarrow \bar{K}^0K^{*+})<Br(D_s^+\rightarrow \bar{K}^{*0}K^+)=(3.90\pm 0.23)\%\) . Our result in the hybrid
method also agrees with this argument.
